Summary
The arrow is pulled back from your face. You let out a breath you hadn't even noticed you were holding in. Your shoulders fall in what you think is relief, but you are completely overcome with dizziness.
It's then, in your dazed state, that Dream, the same man you had just been trying to kill, offers his hand out for you to take.
You blink.
He can't be serious. This has to be some kind of trick, maybe you had actually died, and this is some illusion your mind was playing on you in your final moments.
But despite everything,
Something in you wants so desperately to take his offer.

Summary
A fourteen-year-old dies. Somehow, he wakes up in a gothic castle… in the body of Nightmare Sans. Pale skin, glowing eye, dramatic frills, tendrils that might be alive, and a permanent “I feel miserable” vibe—basically a deluxe, broody skeleton package he definitely didn’t order.
Now he has to survive bad timelines, chaotic skeletons, and his own very confused soul while looking intimidating and not dying… again. Chaos, brooding, accidental gothic flair, and very little actual self-control ensue

- Part 1 of Sans aus for the win! :D

Summary
Nightmare wasn’t at all expecting Dust to confess to him on a random afternoon, and it was odd that Nightmare couldn’t sense it coming. He didn’t believe he harbored the same feelings for Dust, even if he cared deeply for the other. He didn’t think he was ready to date someone so suddenly… So why did he say yes?
And then shenanigans ensue. Shenanigans that might include unpacking your childhood trauma. And also identity crises, it turns out. Maybe more.
Or
Self proclaimed #1 Dustmare Shipper writes a self indulgence fic of mostly fluff and goofiness
(Summary will probably change, since this one kinda sucks lol)
Title is from Line Without A Hook by Ricky Montgomery

Summary
Disclaimers:
Several details in this fic are heavily inspired by 'Blue joins the bad sanses' comic, so go check that out
Canon innacuracies: Passive and Corrupted Nightmare are the same person, Ink is the creator and not the protector, Ink, Error, Nightmare, and Dream, are all gods, Blue, Killer, Horror, and Dust's specific au timelines were all destroyed, and i took liberties with how the void works. Also, no Cross sans will be mentioned, i don't know enough about underverse, and there will be some OC non-sans God/entity/things later on. The fic will be split into parts, each lasting nine chapters.
Schedule: Once a week, on Saturday, Sunday, or Monday, and i will post art or a reference sheet with every chapter. Trigger warnings will be specified in chapter notes. I've never written for undertale before, so please let me know what you guys think :3With that said, the actual plot: After an injured Error crashes into Nightmare and Co's home, a close bond starts to form between the two gods, both forced villains. In light of Ink's attempt to kill Error, Dream finally starts to lose it, and Blue gets dragged along.
Average chapter length is 500-2000

Summary
"He opened several portals in rapid succession[...]even Dusttale#6 for good measure[...]He swore he saw a flash of surprised red eyelights somewhere in that sequence, but eh, that probably would never be relevant to him."
No, it wouldn't be relevant to Check. Nor the Multiverse he dwelled in, not significantly. But that one moment brought DETERMINATION back to the Sans of Dusttale#6, Helvetica. He'd thought his universe cut off from the Multiverse, after losing connection to Underfell#143, when his Universe's code changed from Undertale to Dusttale.
But now, he believed different. He could get Carmine back, despite how much he had changed. Then they could find a way to flee to a different Multiverse altogether, free of the bounds of their Universes, because surely that was what that sight was. A version of himself who had learned to hop Multiverses.
Or; Butterfly effect. (This is a backstory piece to a potential future series. Does include established Dustard/Dustfell. This [unnamed] universe will have more shippy stuff than Checkverse {and is also technically my excuse to show off some of my fav rarepairs})
(VERY much a warmup piece for this AU, shorter than my regular stuff :P)

Summary
(shortened desc - i made the og too long again lol whoops :P)
Dust hated Killer. He hated his stupid smirk, and her teasing words, the stupidly casual tricks with knives. The way Killer was so effortlessly pretty. His empty eyesockets, holding space for galaxies within, her quiet excitement when his SOUL was more normal and she could feel again, his gentle touch as she bandaged Dust's wounds. Dust hated Killer.
Killer hated Dust. He hated his smug grin, and his inane ramblings, the stupidly casual display of his insane magic control. The way Dust was so effortlessly pretty. His shining eyelights, DETERMINATION blazing within, his quiet excitement on kinder days when his past did not haunt him quite as fiercely, his careful touch as he wiped away Killer's tears. Killer hated Dust.
And yet still SOULs fluttered despite genuine frustration. Self hatred directed onto someone so much like themselves, for they were once the same. Everyone dead. Torment. Genocides. And somehow, despite it all, a hand to hold. So what if they got their hands a little dusty?
(Canon to Checkverse. Technically can be read as a standalone, but looks at you with my big sad eyes please pleaseeee read my fics)

Bad At SOUL (But Sweet At Heart) by BlazingFieryMountain

Summary
Filled with LOVE and love. DETERMINATION and HATE. Hope and despair. Willing or not, they ended up in Nightmare's Gang.
In modern days, they hold each other close and bear the brunt of the pain for each other.
But they didn't start out that way. Nothing close to it at all. No, despite their care they hold now, nothing would change their origins, of blood and dust and pain and HATE and LOVE and violence.
This is that story, of how their LOVE softened into love, how painful beginnings beget kind endings all the more sweet for their suffering.
Or; How Nightmare's gang got recruited, and a cruel dictator became a patient parent of four. (Bad Sanses recruitments/backstories.)
